DaveC426913 replied to the thread Undergrad Why is water pressure increased in a plastic bag in a bucket?.I'd kind of like to see the OPs test results duplicated. It would rule out experimental error and also provide some numbers to work... -
DaveC426913 replied to the thread Undergrad Why is water pressure increased in a plastic bag in a bucket?.That is a valid application of without, yes. -
DaveC426913 replied to the thread Undergrad Unexpected findings in need of an explanation (retrograde motion of Mars).That's a darned impressive animation @Sylvain9595! Did you write that yourself? For those that don't follow the provided link, here is... -
DaveC426913 replied to the thread Here to discuss Cosmology.Welcome Amandeep! -
DaveC426913 replied to the thread Undergrad Unexpected findings in need of an explanation (retrograde motion of Mars).Yeh. This was the best I could manage. It's enough to convince me that the OP has a case. -
DaveC426913 replied to the thread Undergrad Unexpected findings in need of an explanation (retrograde motion of Mars).Hm. Wondered about that. I get 404/225px - so still ~1.8:1, no? -
DaveC426913 replied to the thread Undergrad Unexpected findings in need of an explanation (retrograde motion of Mars).And I hope I have demonstrated that it is also immaterial to the answer. No matter how you measure it, it is definitely almost twice as... -

Skeptical.
Wikipedia, referencing a dictionary, not a scientific textbook or paper. Note here that the term "ecliptic longitude" is used, not... -
DaveC426913 replied to the thread Undergrad Unexpected findings in need of an explanation (retrograde motion of Mars).My post 20, rough though it is, should make your assertions self-evident to all. Here, the two images are superimposed and scaled so... -
DaveC426913 reacted to Ibix's post in the thread Undergrad Acceleration calculation in Special Relativity with
Agree.
Do remember that this is relativity theory. An object accelerating from rest to ##v## in one frame is decelerating from ##-v## to rest... -
DaveC426913 replied to the thread Undergrad Unexpected findings in need of an explanation (retrograde motion of Mars).That being said, the next thing I think that needs to be looked at is the geometry involving both their respective aphelia and... -
DaveC426913 replied to the thread Undergrad Unexpected findings in need of an explanation (retrograde motion of Mars).Here they are visualized. I found these starcharts by Google so I'm trusting they're accurate. I used Stellarium to overlay the R/A... -

Like.
But they're asteroids? Where would the implication that they could be hollow space stations even come from? It makes no sense and... -
DaveC426913 replied to the thread Writing: Read Only Have we found an ancient space habitat?.I think I'd get murderized if I try to get it moved to sci-fi... :-p
